Abstract
This study focuses on the symbiotic system between plateau-specific rhizobia and leguminous plants in Qinghai Province, northeastern Qinghai Plateau. Aiming at addressing the current issues in this region, such as farmland nitrogen imbalance, low nitrogen fertilizer use efficiency, and prominent ecological and environmental problems, a multi-disciplinary approach was adopted to systematically explore the nitrogen-fixing mechanism of this symbiotic system, its quantitative contribution to farmland nitrogen balance, and to develop rhizobial inoculants and planting patterns suitable for the plateau. The research provides theoretical and technical support for the sustainable development of plateau agriculture. The results show that the symbiotic system formed by plateau-specific rhizobia and leguminous plants can effectively increase farmland nitrogen input, improve soil nitrogen pool status, and reduce the risk of nitrogen loss. It is of great significance for promoting the development of green agriculture in Qinghai and facilitating the achievement of the "dual carbon" goals.
